refactor: unify formatBytes usage and simplify useContextMenuData

1. Remove formatSize/formatByteSize delegation functions:
   - storageCleaner.ts:formatSize (was just formatBytes wrapper)
   - textStatistics.ts:formatByteSize (was just formatBytes wrapper)
   - Update all callers to import formatBytes directly from @/utils/format

2. Simplify useContextMenuData hook:
   - Remove unnecessary useCallback wrapping
   - Inline checkAndConsumeData logic directly in useEffect
   - Eliminate callback->effect dependency cycle

-69 lines, +67 lines (net -2 lines, but removes 2 indirection layers)
